Question

The proportion of students who own a cell phone on college campus acress the country has increased tremendously over the past few years. It is estimated that approximately 90% of students now own a cell phone. Fifteen students are to be selected at random from a large university. Assume that the proportion of sudents who own a cell phone at this university is the same as nationwide. Let x = the number of students in the sample of 15 who own a cell phone. What is the appropriate distrubution for x?
